This paper introduces a novel design featuring multiple-inclined-orifice restrictor (MIOR) to address the challenge of turbulent vortices and reduction nano-vibrations in aerostatic bearings. optimizes angle configuration alter dynamic airflow patterns within chamber, suppress vortices, mitigate nano-vibrations. Three-dimensional transient vortical structures, pressure fluctuation, load-carrying capacity bearings with varying orifice angles were investigated through large eddy simulations....
This paper presents a new class of flexure hinges, namely, conic-V-shaped hinges (CFHs), which can be used as generalized model for with profiles such parabolic-V-shape, elliptical-V-shape, and hyperbolic-V-shape. Compliance precision equations the CFHs were derived set nonlinear using Castigliano's second theorem. The parameters inputted to compliance matrices based on conic curves in polar coordinates. Furthermore, verified by means finite element analysis experiments. errors experimental...
Aerostatic bearings are widely used in ultra-precision manufacturing equipment as a crucial support component. However, turbulent vortices the recess can induce micro-vibration of aerostatic bearing, which severely affect stability. To further suppress formation and reduce micro-vibration, an bearing with square micro-hole arrayed restrictor (SMAR) was designed influences structural parameters SMAR on its static dynamic performance were investigated using numerical simulations experiments....
Silicon carbide (SiC) is considered one of the most promising emerging materials in fields refractory and semiconductors. In this paper, a multi-scale numerical simulation method proposed to investigate crack propagation SiC at different scales, using combination cohesive zone model molecular dynamics (MD). The microstructure material represented by Voronoi subdivision, bilinear treatment applied grain boundaries. Firstly, MD models with microscopic defects were established obtain...
Abstract The thermal stability of Al 3 BC powders under nitrogen was studied. AlN–BN composites were generated during the nitridation . Possible reaction mechanisms responsible for decomposition discussed. relatively weaker Al–C bonds in promoted fast diffusion and generation layers inhibited deeper nitridation, thus governed by surface reaction. formed nitrides resulted a volume change cracked resulting as reactions progressed, facilitating N 2 enhanced intensive involving could be...
Aerostatic bearings are crucial support components in ultra−precision manufacturing equipment. However, improvements the load−carrying capability (LCC) of aerostatic often lead to higher intensity nano−vibrations. This paper introduces a novel primary and secondary orifice restrictor (PSOR) designed simultaneously enhance LCC mitigate nano−vibrations bearings. The static performance complex turbulent flows occurring within chamber with PSORs was investigated. dynamic analyzed through 3D...
To explore the effect of interdisciplinary chronic disease management (CDM) model on patients with hypertension. In this intervention study, subjects were divided into CDM and control groups. Blood pressure was monitored in both After 1 year follow-up, endpoint events their knowledge, confidence, behavior response to assessed. When compared group, group obtained higher scores for self-perception assessment, blood also better after discharge. The quality life satisfaction level lower than...
